I deal with a lot of buildings in Chicago, so this may not help, but we have a TON of boiler buildings where the owner pays the heat, hot water, cooking gas and water.

The most pressing, and i cant seem to find a true answer from the the building department OR the utility companies is if I need to have separate meters (Electrical, gas, water) for my ADU and main home. 

However, one recent sale in the area was 109K for a .15 acre lot, however, it was verified developable and had gas, electric, and water at the street.

Note: the $1423 amount includes owner paying for electric, gas & water.

The wholesaler and seller represented this duplex as having two separate water meters and two separate gas meters.

Also, a colder climate is better for DC.So from this aspect we can see something that's not too obvious, while the job and population is moving to the south, data center or internet data is actually moving to the north lol You have LNG coming on in 2026-2027, making natural gas even more globalized as a commodity.

Utilities If you haven’t already set up utilities, then connect your water, gas, electricity, and Wi-Fi.

Tree clearing, grubbing, moving dirt for cut/fill operations, storm water, power, gas, water, fire access etc. not a small task but doable.  

Roseville has their own utilities except Electric gas, you can't go wrong.

Wow what a gas and the power of cell phones!!
